Why are we doing this course?


The globalization of ayahuasca outside of its Amazonian context has generated new potential benefits, as well as potential risks that affect guides, participants, and the plant community as a whole.

This can involve physical or psychological risks, drug interactions, dangerous interpretations of experiences, or more subtle issues such as dual relationships between guides and participants. Plant medicine sessions in the Global North can bring certain challenges which often do not arise in traditional contexts.

Finding valid information on these topics is not easy. Many facilitators working outside the Amazon don't have easy access to support from doctors, psychologists, and other professionals.

In this context it is essential to incorporate a harm reduction perspective and prevention strategies to minimize the potential consequences that legal or illegal plant consumption could pose to individuals or societies.

That is why ICEERS presents this prevention initiative to increase safety for people who are working with plants outside the countries of origin.



For more than a decade ICEERS has been hosting dialogues between facilitators, participants, clinicians, researchers, psychologists, and psychiatrists about ayahuasca safety and ethics.

Our Support Centre has handled more than a thousand inquiries on integration and medical questions. 

All this knowledge was distilled into this easily accessible online course we are now offering to the community.


Our eight-module program covers the most important considerations for increasing safety for facilitators and participants. The course combines theoretical learning with live dialogues with instructors.
